i installed them under the little lip of each bench seat running port to starboard. it should illuminate the floor/lower area of my boat. they face downwards so they shouldnt be too bright on the eyes, i have yet to test them in the dark becuase i installed them earlier this week, then had to put the cover back on my boat because of this spring snow storm we just had. i dont have pics of them yet, but i can take a view in the next couple of days. aside from them being sticky on one side, i also used clear silicone caulk as an adhesive, that should keep them pretty well adhered to the boat. i am also going to install red ones next week. pics of those to come also.
